Blood flows from right atrium to the right ventricle where it is pumped to _____

1 answer:

8 0

Blood always flows through the system in the same pattern: coming from the body, passing through the right side of heart, then out to the lungs to receive oxygen, then passing back through the left side of the heart and then traveling out to the body. Heart valves help to keep the blood flowing properly to each important destination of the circulation journey.

Under which type of change in the ecosystem ( fast change or slow change) would more organisms be able to survive and why?

TiliK225 [7]

Answer:

slow change

Explanation:

If the change is slow they have time to adapt. An example of a fast change is human deforestation. With their habitat suddenly removed, the organisms living there will have to find new shelter and food fast. It's likely that they'll not even be able to find anything to survive off of and die, because organisms tend to have very specific needs. For example, pandas would go extinct if bamboo was eradicated.

Freshwater fish would not be able to adapt if it was suddenly dropped into salt water. They would die. An example of a slow change would be the slow addition of salt to freshwater. Fish that are better able to survive within higher levels of salinity will be more likely to reproduce. Slowly through reproduction a new type of fish suited to salt water may be developed over several generations.

In mosses gametes are produced by _____; in ferns gametes are produced by _____.

Zepler [3.9K]

Answer: Mosses gametes are produced by mitosis and ferns gamete are also produced by mitosis.

Explanation:

Mosses and ferns are bryophtes, a group of plants that live in moist habitats and lack true leaves and root.

Mitosis is a form of cell division where a single cell divides to produce two identical daughter cells.

During the life cycle of ferns, the diploid sporophyte produce haploid spores by meiosis. The prothallus of the sporophte produce gametes by mitosis.

In mosses, the diploid sporophyte produce spores from a capsule which open when a small structure operculum degenerates. A single spore germinate to form protenama from which the gametes are produced through mitosis.
